Tube Couplers are used primarily to join Body Tubes (Air Frames) together. They fit firmly inside Body Tubes.
Tube Couplers are also great to create capsules for carrying various payloads.
Available in a range of internationally recognised sizes, these are manufactured using a spiral wound technique with strict tolerances to ensure there is no lateral seam.
